JOHN A. MGGREEVEY, OF DELPHI, INDIANA.

DRIVEN WRENCH.

To all whom it may concern:

Be it known that I, JOHN A. MoGREnvnY, a citizen of the United States,residing at Delphi, Carroll county, Indiana, have invented a new,useful, and indispensable Driven rench Adapted for Use in Land-Anchoring, of which the following is a specification.

My invention relates to land-anchoring and is the means or tool fordriving the anchor into the ground to any desired depth then twisting itin such manner as to have it securely fastened, thus making the anchorsto posts, poles, etc., more diiiicult to be displaced than if they weremerely driven into the ground and not twisted in this manner.

The prime object of my invention is to provide a driven-wrench adaptedfor all purposes for which my driver-rod and wrench, for which Iobtained Letters Patent, numbered 991,525 for land-anchoring, bearingdate of May 9, 1911, was presumed to serve, and especially to preventthe injurious efiects of the rigorous vibrations of the handle on thatdriver-rod My invention will be more clearly understood from theaccompanying illustrations, in which Figure 1 shows a full side view inperspective, showing the driven-wrench co1n plete in form and indicatinghow the sleeve portion of the handle, being slightly flattened aroundthe top portion of the driverrod, works loosely thereon, as is moreclearly shown in Fig. 5. Fig. 2 shows an end view of the handle, thedriver-rod bent at its top so as to fit closely against the rod abovethe handle forming a head on which the drivenwrench is driven, and also,shows the groove in the sharp end of the rod in which the cable to bedriven into the ground is held securely in place until it has beentwisted as required and then released from the rod, as shown in Fig. 6.Fig. 3 shows the relative shapes and positions of the three parts,respectively, the driver-rod, the looped center of the cable supportsand theaboveground cable wire attached thereto. Fig. 4c shows the cablepresumed to be in the ground and twisted one-fourth of a full turn ofthe driver-rod. Fig. 5 shows the handle. Fig. 6 shows the flattenedposition of the driverrod about which the handle loops.

Similar numerals refer to similar parts throughout the several views asillustrated.

Specification of Letters Iatent.

Application filed November 13, 1911.

Serial No. 660,141.

In Fig. 1, 1 is the driver-rod, 2 the handle thereon, which handle ismade of one piece of. metal formed to loop at 4, around the driver-rodand is riveted to itself at 3, as shown.

In Fig. 2, 6 shows that portion of the top of driver-rod which has beenbent over and downwardly against the rod closely for the purpose offorming a less vibratory head 12, upon which the driver-rod is drivenwith sledge, hammer, maul, etc., and shows the groove or jaws betweenwhich the looped portion of the cable 8, is engaged at 9, the extendedportions 10 and the engagement of the guy wire or cable 8 at 11 all ofwhich as shown in Fig. 3, and in which relative positions the anchorageis ready to be driven by the driven-wrench to the desired depth in theground.

Fig. 4: shows the form the cable supports 10 assume after having beendriven into place and twisted by the driven-wrench into this form ashereinbefore described.

I have herein referred to Figs. 3 and a as illustrations in my formerpatent as hereinbefore mentioned, but do not claim any part of them aspart of this invention.

My driven-wrench is operated as follows :The looped cable is formed withits projecting ends as supports, the guy wire or aboveground wire isfastened to the cable loop, the loop is placed within the jaws of thesharp end of the driver-rod, the driven wrench is then driven to thedesired depth into the ground, then by the handle is twisted one-fourthof one full turn of the driver-rod, and the driven-wrench removed.

This form and construct-ion of handle permits the operator to direct thecourse of the cable being driven to any desired angle, and eliminatesthe rigorous vibrations of the handle as constructed in my former patentin and to the degree that this handle is easily held while thedriven-wrench is being driven, whereas the handle in my former patentmade it unbearable to the hand when the cable was being placed in theground. Experience shows that no construction of a handle, save thisinvention, is practicable for this purpose.

Having thus fully described my invention, what I claim and desire toprotect by Letters Patent of the United States, is

A driven-wrench of the class described comprised of a driver-rod groovedin its sharp end, said groove adapted to carry the driven-Wrench isdriven substantially as between its jaws and against its base, wirecables designed to be driven into the ground and twisted therein, saiddriver-rod provided with a loosely fitting handle as especial means ofeliminating the effects of severe vibrations, said driver-rod having aportion at its top end flattened and a further top portion bent to fitdownwardly rigidly against itself forming a head upon which describedand for the purposes set forth.

In testimony whereof I have hereunto subscribed my name in the presenceof two subscribing witnesses.
